Amita Toprani, MD, MPH New York City Department of Health & Mental Hygiene EIS Field Assignments Branch Centers for Disease Control and Prevention CSTE Conference June 4, 2012 Patient Characteristics of Repeat Induced Terminations of Pregnancy — New York City, 2010 Office of Surveillance, Epidemiology, and Laboratory Services Scientific Education and Professional Development Program Office

Why Study Repeat Abortions?  Majority of abortions result from unintended pregnancy  Repeat abortion = repeat unintended pregnancy  Women undergoing abortion are high risk group for future unintended pregnancy  Little known about women who undergo repeat abortions  Opportunity to provide long-acting reversible contraceptives

Abortions are Reportable to the NYC Bureau of Vital Statistics  NYC Health Code requires abortion reporting  Within 5 days of event  Definition of abortion  Purposeful interruption of intrauterine pregnancy  Intention other than to produce live-born infant  Does not result in live birth  80,000 abortions reported yearly  Estimated to capture 88% of procedures

Abortions are Reportable to the NYC Bureau of Vital Statistics  Healthcare provider or designee completes report form  Self report of past pregnancy outcomes  Abortions, miscarriages, and births  Demographic and socioeconomic data  Patient age  Level of education  Race/ethnicity  Method of payment  Zip code  Marital status

Questions  How common are repeat abortions in New York City?  What characteristics are associated with repeat abortions?

Methods  Inclusion criteria  Procedures among NYC residents  Performed during 2010  Outcome of interest: repeat abortion  Procedure where the patient reported a history of one or more prior abortions  Rates of first and repeat abortion  Age  Race/ethnicity  Neighborhood level poverty

Descriptive Analysis Methods  Proportion of all abortions that are repeat procedures by:  Stratified analysis  Race/ethnicity and neighborhood-level poverty  Patient age  Level of education  Race/ethnicity  Method of payment  Neighborhood-level poverty  Marital status  Number of living children

 Predictor variables  Outcome: Mean number of prior abortions  Negative binomial regression with single predictor Bivariate Analysis Methods  Patient age  Level of education  Race/ethnicity  Method of payment  Neighborhood-level poverty  Marital status  Number of living children

Bivariate Analyses Variablep value Age<0.0001 Race/ethnicity<0.0001 Neighborhood-level poverty<0.0001 Number of living children<0.0001 Level of education<0.0001 Method of payment<0.0001 Marital status0.7980

 Negative binomial regression  Outcome = mean number of prior abortions  Predictor variables significant in bivariate analyses  Education variable removed due to 21% missing Multivariate Analysis Methods

Multivariate Analysis  All predictors significant after adjustment  Patient age  Number of Living Children  Race/ethnicity  Method of payment  Neighborhood-level poverty

Discussion  Patient age  Number of living children  Race/ethnic disparities  Economic disparities

Limitations  Self report of abortion history  Unit of analysis is abortion event, not woman  Missing values  Cannot exclude medically indicated abortions

Conclusions  Repeat abortions comprised over half of all abortions  Repeat abortion common across all sociodemographic characteristics  Race/ethnicity strongly correlated with repeat abortion

Next Steps  Identify interventions to integrate with abortion visits  Include post-abortion contraception in surveillance  Reduce barriers to provision of long-term contraception  Further research needed on race/ethnic disparities
